W'ALL CONSTRUCTION.

Application filed October 2"?, 1924, Serial No. 746,076. Renewed September 19, 1925.

T0 all whom t may concern Be it known that I, FRANK li/ioh/liUnnAr SAwrnR, a citizen of the United States, residing at Miami, in the county of Dade and State of Florida, have invented certain new and useful Improvements in Wall Construe tions, of which the following is a specification.

ri`his invention relates to improvements in wall constructions, and has for its object to provide a strong and durable wall formed with a plurality of coreless units which are made a plural-mold wherein a series of the units can be cast or molded in a single mold.

Another object is to form a wall of standardized units of comparative lightness, which are easy to handle, and thereby obtaining a. saving in material, and also arranging said units in a manner to secure a wall of great strength and desirability.

These and other objects hereinafter set forth are attained by the means illustrated in the accompanying drawing, in which:

Figure 1 is a perspective view of a portion of a wall, and

Figure 2 is a like view of one of the tiles or units with which the wall is formed.

Similar reference numerals in all of the figures of the drawing designate like parts.

As shown in the drawing, each t-ile or unit is formed with a longitudinal leg 5, a transverse leg 6 extending at right angles from one end of the longitudinal leg, and a longitudinal extension 7 projecting from the other end of the longitudinal leg 6 in alinement therewith and preferably with its outer face forming a continuation of thel outer face of the leg 6.

The transverse leg 6 is formed with a notch 8 on its inner face at the extreme end of said leg, and the longitudinal leg 5 is formed with a notch or undercut 9 at its extreme free end at a point where the longitudinal extension joins lsaid leg, the tongues l0 and ll formed by these ynotches in the respective legs are adapted to interlock when the tiles are arranged in position in the wall.

The longitudinal extensions 7 are preferably formed thinner than theleg portions of the tile, so that, when the tiles are arranged in the wall with the extensions opposite each other, a wider space is formed at this point than between the main portions of thelongitudinal legs, thereby a space is formed which when filled with concrete will form a solid column nearly as wide as the Wall, the thin extensions forming a facing for said columns. This is necessary to secure a greater strength for the columns.

To form a wall with these units, the tiles are laid on their edges in pairs and in courses with the tiles in each pair reversed with respect to each other, so that the longitudinal legs of each pair form the inner and outer faces of the wall, and with the longitudinal extension of one title projecting beyond the transverse leg of the opposite tile to form a column space between the transverse legs andthe extensions of adj acent tiles. The tiles in one course are arranged in a reverse position from the tiles in the adjacent courses, and are also staggered with relation to each other to stagger the vertical joints l0, as shown clearly in Figure l of the drawing.

When each pair of tiles are placed in position, the tongues l0 interlock with the tongues 1l of the opposite tile, thus effec-tw ally preventingl the inner and outer tiles from spreading laterally with respect to each other.

At the intersections of the tiles where the extensions 7 are thin, the grout is poured to form the vertical columns l1 which extend the entire height of the wall, and the thin walls permit the front and rear edges of the columns to lie close to the inner and outer faces of the wall, and vertical reenforcing rods l2 are preferably embedded in the columns close to their front and rear 'edges approximately in alinement with the inner faces of the longitudinal legs.

4The thickness of a wall is determined by the length of the legs 6 plus the thickness oi the longitudinal extensions 7.

l/Vhen the grout is poured to form the vertical columns, it seals every vertical joint of the-walland ties the tiles to the columns and to each other, thereby forming a wall of great strength and desirabilitye With this construction the tiles can be made rela-- tively thin, thereby saving in the amount of material used. The walls may be pointed up and be left as thus finished, or they may be plastered, and if plastered, it is unnecessary to place mortar in the head joints as i the poured grout seals these joints.

lVhat is claimed is i-e y l. hollowwall construction, comprising a series of tiles each having two legs, the tiles being arranged iii pairs and in reverse pcsitiilii each other te ferm. the irmeand outer faces of the wall, each of said tiles he ing formed with a loc-king ineans at the end of each leg which are adapted to interlock with similar locking ineanson the leg-s of the other tile of the pair.

2. A hollow wall construction, comprising a series of tiles each having two legs, the tiles being arranged in pairs and -in reverse position to each other to forni the inner and outer facesvof vthe wall, each of -said tiles being formed with a locking ine-ans at the end of each leg which are adapted to interlock with similar locking ineans on the legs of the other tile ofthe pair,.and one of the legs of each tile bein-g provided with a longitudinal extension which is ada-.pted to rextend beyond the transverse leg of the opposite tile.

3. Ar hollow wall construction, comprising a series ot tiles each having two legs, the tiles being arranged in pairs and in reverse position to each other to form inner and outer faces of the wall, each of said tiles be- -ingforined with a notch forining a tongue at theend of each leg thereof, said tongues of one tile adapted to interlock with the'tongues of the -other t-ile of the pair to prevent lateral spreading of the tiles with respect to each other.

l. A hollow wall construction, comprising a lseries of tiles each having two legs, the tiles being arranged in pairs and in reverse position to each other to forni inner and outer faces of the wall, each of said tiles being formed with a notch forining a tongue at the end of each leg thereof, said tongues of one tile adapted to interlock with the tongues of the lother tile of the pair to prevent lateral spreading of the tiles with respect to each other, the notch in one of the legs of each tile being formed in the end thereof at the `junction of the longitudinal extension.

A hollow wall construction, comprising a series of tiles each having two legs, the tiles being arranged in pairs and in reverse position to each other to forni inner and outer faces of the wall, each of said tiles being fornred with a notch forming a tongue at the end of cach leo' thereof, said tongues of one tile adapted to interlock with the tongues of the other tile of the pair to prevent lateral yspreading ofthe tiles with respect to eac-h other, the notchinone of the legs of each tile being formed in the end thereof at t'he junction of the longitudinal extension, and said longitudinal extension being formed of less thickness than its'leg to perinit theend of the transverse leg to partially overlap the end of the longitudinal leg.

'6. Ahollow wallconstruction formed of a plurality of angular tiles each having two legs and laid in courses, the front and rear tiles in each course being reversed with re spect to each other, the tiles in one course having their longitudinal legs extending further in opposite directions from their transverse legs than do the longitudinal legs in adjacent courses, each pair of opposite tiles forming a hollow space which is lcontinuous vertically through the wall, and the longitudinal leg of each tile being formedwith an extension to project beyond the transverse leg of the opposite tile, and a concrete lilling forining vertical supporting columns between said extensions ,and the transverse legs adjacent said extensions.

7. A. hollow wall construction formed of a pluralityv of angular tiles each having two legs and laid in courses, the front and rear tiles in each course being reversed with respect to each other, the tiles in one course having their longitudinal legs extending further in opposite directions from their transverse legs than do the longitudinal legs in adjacent courses, each pair of opposite tiles forming a hollow space which is continuous vertically through the wall, and the longitudinal .leg of each tile being formed with an extension to project beyond the transverse leg of the opposite tile, and a concrete filling forining vertical supporting coluinns between said extension and the transverse legs adjacent said extensions, the transverse legs in one course being positioned in alineinent with the opposit-ely extending transverse leg in adjacent course, so that the tiles in adjacent course will be staggered with relation to each other.

8. A tile `for forming hollow wall con structions, comprising a longitudinal leg and a transverse leg forined at right angles to each other, said longitudinal leg being forined with .a longitudinal extension and a vertical notch at the .base of said extension, and said transverse leg being also provided with a vertical notch on its inn'erl'ace adjacent its free end, said notches forming vertical tongues adapted to .interlock with like tongueson another tile placed opposite.

In testimony whereof l affix iny signature.
